Boffins are working on sniffing out alien life by building a mammoth telescope capable of detecting ETs’ farts.

Scientists are developing the mega Habitable Worlds Observatory (HWO) scope to boldly go way beyond Uranus in the hunt for little green men. It will analyse light beams from the atmospheres of rocky Earth-like planets outside our solar system.

Eggheads say the HWO will be able to tell if oxygen – and the fart gas methane – has passed through or been absorbed by the far-off light waves. If they pick up planets with both signs they say it is almost certain it will contain aliens.

NASA’s Exoplanet Exploration Program chief technologist, Nick Siegler, said: “We want to probe the atmospheres of these exoplanets to look for oxygen, methane, water vapor, and other chemicals that could signal the presence of life.”
